The international event is coordinated by the ICPDR, but organised nationally and locally by state, regional and local authorities, NGOs and corporate partners.
It is a celebration of a cleaner, safer river following 20 years of international water cooperation. Huge festivals on the banks of the rivers; public meetings and fun, educational events pay tribute to the Danube rivers, its peoples and the progress that has been made.
